With FF open with several tabs (four in the last case), PC running, no antivirus, the history gets wiped out, bookmarks stay. The "places.sqlite" file is still the same date but the other four files at 2:pm suddenly changed (PC did not go to sleep, I was still using it).

Profile data can be removed or not recorded several ways;

  • 1) Running Firefox in Private Mode (nothing is recorded)
  • 2) Privacy settings; (In the address bar, type about:preferences#privacy<enter>)
  • 3) Many disk cleaners and anti-virus type programs can remove data from browsers. Open their settings and have them leave the browsers alone.
  • 4) Mal-ware.

The files with a sqlite-shm and sqlite-wal file extension are SQLite temp files.

wal: Write-Ahead Logging
shm: Shared Memory files

These files shouldn't cause dataloss under normal conditions and are best left alone.
